  • the emergency alert pager system is particularly suited to college and public school campuses, groups of law enforcement resources at national events, business campus environments, and the like.
  • the emergency alert pager system is designed to address critical incidents where mass notification of threat information has to be disseminated at extreme speed.
  • the emergency alert pager system allows for two-way communication between individuals and a dispatch center. That is, an individual can send an alert or alert message to the dispatch center and the dispatch center can send an alert or alert message to an individual, a group of individuals, or all individuals on the system.
  • the emergency alert pager system is preferably a stand alone system utilizing its own networks and communications equipment and protocols. Thus, there is no reliance on third party equipment and networks, allowing for faster and more reliable delivery of alerts and/or alert messages.
  • the emergency alert pager system is particularly well suited for protecting groups of people within a specified area, but is simultaneously effective for use as an alert system capable of providing individual security.
  • the emergency alert pager system could notify all 30,000 people in less than one second of sending the message.
  • the campus shooting rampage actually took place about two hours after the initial double homicide, but students and faculty /staff were not notified of the threat in time to avoid the ensuing tragedy.
  • a dispatch center equipped with the emergency alert pager system main controller / monitoring station could receive instantaneous alerts from each person equipped with a personal alert pager device in the threat area.
  • the dispatch office can use the main controller to send an alert to every other person having a personal alert pager device, alerting everyone on campus in less than one second.
  • Each alert received by the main controller can be displayed on a monitor, preferably with each personal alert device represented by points of light on a graphical map screen representing the whole campus. As the points of light appear, as alerts are being received instantaneously, the dispatch center can alert first responders to the exact location of numerous threat origination points- the exact location being indicated by the GPS position of the personal alert pager device sending the alert. Additionally, the monitor can also "poll" each personal alert device if desired, to determine the exact location of each personal alert pager device, even such devices which have not sent an alert to the main controller.
  • the main controller can also send a warning alert of the threat area to every person on campus in under one second, if they have the personal alert pager device.
  • the points of light graphically representing every alert sent from a personal alert paging device also can trace a "path" that the threat is taking, thereby speeding up the response of law enforcement. The exact location of each point of light will be displayed as the GPS coordinates of each personal alert pager device that transmits an alert to the main controller.
  • RFID technology can be added to multitask with the personal alert pager device, allowing the device to be used for gaining access to buildings, secure areas, and the like which can be designated as safe areas for people to seek refuge from the threat.
  • each personal alert pager device cannot only receive an alert, it can send an alert to the monitoring station. Consequently, the personal alert pager device can also serve as an individual panic alarm in the case of an attack, assault, abduction, and the like.
  • the two-way alert capability i.e., two-way communication between the personal alert pager device and the monitoring station, is believed to be unique to the emergency alert pager system.
  • the system 10 generally comprises:
  • each in 2-way communication with the base station 12, and each pod 14 comprising (as described in more detail below in connection with Sheet 2/2) one or more of a transceiver 26 and associated antenna, a GPS module 28 and associated antenna, text display screen 30, and alert buttons/switches 32.
  • the system is comprised of at least one portable unit 14, but preferably many portable units 14, or pods, and a single main security controller 12 (which may alternatively be referred to as a main controller, master controller, monitoring station, or base station).
  • Each pod 14 can be handheld or wearable by a user.
  • the main controller shows the pod on a screen 18 along with pertinent information.
  • the main controller can send back a message to the individual pod or a general announcement to all pods. If a pod user is missing, their pod can be polled as to its whereabouts and status.
  • Pods can be deployed in a wide screen search, and repeaters can increase the range of the system.
  • the emergency alert pager system described herein can generally be comprised of the main controller that monitors and processes emergency calls from multiple sources, primarily large numbers of portable units (which may alternatively be referred to as a personal alert pager device, or a pod).
  • the system preferably utilizes a private area wireless network, mainly for reasons of speed and robustness, and avoids all the disadvantages of public service networks.
  • the pods can number up to 250 thousand.
  • Each pod can be roughly the size of a small cell phone, and can include, inter alia, a complete spread spectrum digital transceiver system, a high sensitivity GPS receiver, and a visual and audible alert complete with vibrating silent alert.
  • the visual alert can comprise, for example, a two line alpha numeric display (which can be an LCD display) which can deliver detailed threat information and emergency instructions to all units in under 30 seconds.
  • the emergency alert pager system can use pager technology with one or more of a variety of alert notification systems, such as text messaging on LCD display screens, audible alert tones, vibrating alerts, and GPS technology as well as RFID (radio frequency identification) technology.
  • alert notification systems such as text messaging on LCD display screens, audible alert tones, vibrating alerts, and GPS technology as well as RFID (radio frequency identification) technology.
  • RFID radio frequency identification
  • the pod is unique in that it can not only receive an alert (by text, vibration alert, or audible alert) from the base or monitoring station, but can also send an alert to the monitoring station, via a spread spectrum transceiver, for example, by activation of one or more switches, buttons, or the like.
  • An alert may be a message, for example, "emergency", "need assistance”, or the like.
  • Each pager-like pod can also be tracked by GPS, and can thus be located by the monitoring station after an alert is sent to the base station.
  • the GPS information from the last valid fix is transferred to the controller in under one second, along with the ID number of that pod.
  • the average, untrained person could forget their own name, much less their relative position in relation to the event.
  • the GPS position is vital information that is gathered from each pod.
  • the main controller can simultaneously send instructions to select individual pods, or a general broadcast to all pods, or all pods in a certain area. If desired, pods can be prioritized by groups or individuals (teachers, security staff, administration, and others). Each pod can have a unique identification code. The system can also be used for general announcements to the student body/faculty or page a specific individual in the network in under one second from the message being typed.
  • Each pod can also be provided with RFED keycard type system capability for ingress to buildings, as well as restricted or secure areas.
  • the RFID capability which functions similar to bar coding, can enable the pod to "scan" across a receiver such as a card reader to electronically unlock secure doors.
  • the software interface can comprise, inter alia, a database containing identification (ID) information for each device within the specified area being served by the system, and can include graphic mapping for a specified area that all the pods operate within. This can be displayed as a map on a computer monitor associated with the main controller, wherein each pod can be displayed as a "points of light" on the map. Depending on application, each pod can appear as a point of light when an alert is sent to the monitoring station, when the pod is alerted by the monitoring station, and/or when the pod is queried by the monitoring station.
  • the main controller software can be designed to provide a dropdown window containing information including current GPS coordinates for each pod.
  • the pod can be configured to transmit its GPS location to the main controller both when the pod sends an alert to, and when it receives an alert from, the main controller. Additionally, the main controller can "poll" or "ping" the pod to determine its GPS location. Thus, if a user/pod is unaccounted for, the pod can be pinged to activate the pod to transmit its GPS coordinates to the main controller. Each pod can also store a history of its GPS coordinates, in case there is a need for that information. Line of sight range is in excess of three (3) miles, and repeaters can be used for extended range or blind spots behind obstructions. The pods are rechargeable, and will last up to three (3) days on a single charge.
  • the pod 14 is broadly illustrated and can generally comprise:
  • the pod can be configured to send an alert to the base station, for example, by pushing two buttons (switches) at the same time.
  • a specific button sequence can also be programmable to the system or user's preference.
  • the buttons can be recessed into the case to prevent accidental alerts.
  • the pod transfers information to the master controller, for example, using a state of the art, embedded spread spectrum transceiver.
  • the transceiver preferably transmits in the 900 MHz region at a power level of approximately 250 mW. This level of power ensures a line of sight range in excess of two (2) miles.
  • the use of spread spectrum technology rapidly changes the transmit frequency many times a second. If there is an in band signal, either noise or active jamming, this makes the transmission much less likely to be interfered with. If a transmission is received intact, an acknowledgement is sent by the master controller. If, for some reason, the transmission is not properly received, it will be resent, for example, up to 26 times, to complete transmission.
  • a text type keypad can be installed on the pod, which provides the capability to send more detailed information to the base station.
  • a text type keypad can be installed on the pod, which provides the capability to send more detailed information to the base station.
  • the latest generation of GPS chipsets uses an extremely high sensitivity and high speed correlator to decode the available GPS signals. Combined with a very reliable helically wound antenna, the system can lock onto very weak signals. The need to be outdoors, in a large field with no obstructions of the sky, is a thing of the past. Indoor fixes of position are much more reliable. The GPS unit can simultaneously track up to 20 satellites for very accurate positional information.
  • the pod If the pod loses "sight" of enough satellites for a fix, it will transmit the last good fix received, along with the time of the fix. This gives the main controller (and the first responders) more information than just the pod ID number— it provides a place to begin the search.
  • the pod can be tracked using RF tracking techniques to recover the pod. All pod IDs are encoded, so the possibility of an unauthorized user tracking a pod is very unlikely.
  • Alerts can be sent to one or all pods simultaneously, with audible, silent, tactile and/or text messaging format.
  • C. Alerts are extremely high speed, unlike typical text messaging systems relying on email or cell-phone devices.
  • Each pod is traceable by internal GPS modules in every pod.
  • each pod can be displayed as a point of light on a computer monitor to immediately reveal the exact GPS coordinate of each pod sending or receiving an alert.
  • the points of light appearing on the main controller monitor serve as real-time threat locaters enabling real-time threat tracking, by means of each additional alert being sent to the main controller as the threat moves within the service area, such as a college campus, other compounds, or other types of areas.
  • the pods can be RFID-scanning capable for gaining entrance to safe or other secured areas.
  • the pods can be identified with individual data saved in a separate data-base that works in conjunction with the main controller; a "mouse-over" feature can be programmed to allow the controller to identify the registered user of the alerting pod as it appears as a point of light on the monitor.
